What is Asthma?
Asthma is a chronic respiratory condition that affects the airways. It causes inflammation, narrowing, and swelling of the airways, making it difficult to breathe.

- Shortness of breath
- Chest tightness
- Coughing, especially at night or early in the morning
Causes of Asthma
The exact cause of asthma is not known, but it is believed to be a combination of genetic and environmental factors. People with a family history of asthma are more likely to develop the condition, and exposure to certain environmental factors such as air pollution, tobacco smoke, and respiratory infections can also increase the risk of developing asthma.
Triggers of Asthma

Diagnosis of Asthma
Diagnosing asthma involves a physical exam, a review of your medical history, and various tests. These tests may include lung function tests, such as spirometry, and allergy tests to identify potential triggers. Your doctor may also ask you to keep a diary of your symptoms and triggers to help diagnose asthma.
Treatment of Asthma
The treatment of asthma typically involves a combination of medications and lifestyle changes. Medications used to treat asthma include:
- Inhaled corticosteroids
- Long-acting beta-agonists
- Leukotriene modifiers
- Short-acting beta-agonists
Lifestyle changes that can help manage asthma include avoiding triggers, quitting smoking, getting regular exercise, and maintaining a healthy weight.
